Winds may be light enough and incoming background levels high enough for ozone levels to reach "Unhealthy for Sensitive Groups" on the south and southeast side of the Houston and Dallas-Fort Worth areas, on the north and northwest side of the Austin and San Antonio areas, and in the Corpus Christi area, "Moderate" or possibly higher levels in the Beaumont-Port Arthur and Victoria areas, and "Moderate" levels in the Brownsville-McAllen, Laredo, Tyler-Longview, and Waco-Killeen areas, with highest concentrations this afternoon and into the early evening. Incoming continental haze should keep PM2.5 levels in the "Moderate" range over parts of Southeast Texas, including the Houston area. Elsewhere in the state, moderate winds and lower incoming background levels should help to keep air quality in the "Good" range.
